good subject! but i do'nt know if it was your intention to focus on the left part of the flower, but i think it would have made a much better image if you closed your aperture a couple of stops to bring more of the flower into focus, or perhaps move in a little closer but change the angle and still included some of those rusty nails in the background.

Nice shot. I like the repeating nails. I wish there was more detail on the stem. Also, I'm not crazy about the plant/flower blurring on the upper top right. Perhaps the image could have been taken a little bit to the left (because the plant overlaps a nail).
